Ok, I now consider myself in trouble then.

Btw, could you give me some hints regarding the Blackfin project policy
for updating svn://sources.blackfin.uclinux.org/linux-kernel and/or
git://sources.blackfin.uclinux.org/git/readonly-mirrors/linux-kernel.git?
Is the latter still a pre-mainline staging tree pulling from the former?

More specifically, which one shall I pull your changes from?
(the blackfin.uclinux.org seems currently unreachable).

TIA,
